to interfere in a trade dispute involving us and canadian aerospace companies? the backlog of cancellations grow at rya nair with hundreds of thousands of passengers affected. we talk you through what's at stake. welcome to world business report. i'm sally bundock. also in the programme, we look at the tech—savvy toddlers who put silver surfers to shame. uk prime minister theresa may is meeting justin trudeau in ottawa today. she's expected to side with canada in a sensitive dispute with the us that has tested trade relations between the two countries. it's between canadian company bombardier and the us plane maker, boeing. so, why is the uk wading in? samira hussain has more from new york. this story starts in 2016 when the

canadian aerospace company bombardier on a contract to supply 125 c series passengerjet bombardier on a contract to supply 125 c series passenger jet to bombardier on a contract to supply 125 c series passengerjet to the us airline delta. the american rival boeing says the deal was not fair, since bombardier agreed to sell the majority of those planes below their cost price, a practice known as price dumping. boeing has taken their complaints to both us and international trade authorities. this is clearly a fight between canadian and american company. so why the british prime minister theresa may phone us president donald trump last week about this particular trade dispute? turns out the canadian firm is one of northern ireland's largest employers. the wings and fuselage of bombardier‘s c

series and manufactured in this factory. if the trade dispute and the jeopardising the contract, it could cost northern ireland's small economy hundreds and hundreds of jobs. the fact is nascar, whether it is mexico or canada, is a disaster. —— nafta. it is a disaster. is mexico or canada, is a disaster. -- nafta. it is a disaster. a trading disaster. the relationship isn't as frosty as donald trump suggest that there are outstanding trade disputes between us and canadian dairy farmers, the decades long fight over softwood lumber, and 110w long fight over softwood lumber, and now planes. there is however some speculation that boeing will eventually backed down. between us and canada trying to effectively renegotiate nafta and canada is a really strong partner with the united states in negotiation, alienating and isolating canada at this moment is not in the us‘s

interest. 50 how will the us react to the uk's involvement in this particular trade dispute? well, it could go either way. donald trump could go either way. donald trump could see a minister may‘s actions as an opportunity to build bridges. 0r as an opportunity to build bridges. or he could see it as foreign intervention, reject the request, and take his feelings to twitter. with me is professor david collins, at city university. good to have you with us. how do you think this will play out? i'm hopeful it won't escalate to a full trade dispute through nafta or other forums so i think this will probably be contained at the diplomatic level through these kinds of overtures by theresa may and perhaps prime minister trigger of or else through formal negotiations through the trade lawyers basically — justin trudeau. if for example it would go

down the legal rout, canada and the uk could point the finger at boeing in terms of subsidies, but the us could point the finger at airbuses well. bombardier has a long history of receiving extensive subsidies by the canadian government. the federal government as well as the government and province of quebec, and the reason for this is historically quebec carries a lot of political weight, quite similar to northern ireland actually, is an interesting parallel. for there's obviously a potential that this could lead to the level of being a full dispute if there's something like nafta because of the importance politically of the issues. this is the kind of thing that obviously donald trump is worried about the employment in the aerospace in the us and justin trudeau is worried about similar for canada. but the reality is a full on trade dispute would be quite problematic because as you point out boeing has received subsidies,

airbuses has received subsidies and in europe we had a wto dispute for many years, and i don't see why they would raise it to this level because it would be a bloodbath, everyone would be suing everyone, so why not contain it diplomatically before it gets to that level? what is the relationship like between donald trump and justin trudeau given the point in that report that donald trump prides himself on being a lack of and shortly afterwards vitriolic about the nafta agreement?” of and shortly afterwards vitriolic about the nafta agreement? i think the relationship between president trump and justin trudeau is quite good and the somewhat unusual because they come from different points of the political spectrum so i don't see there being a problem there but if anything there is goodwill there and i suspect the same is true between president trump and theresa may. this is a great deal of human capital which can be drawn upon the present, prevent ex—

— — exa ctly drawn upon the present, prevent ex— —— exactly this kind of dispute. so i'm hopeful these overtures could work and i could be wrong and i think the point in the piece there is to watch donald trump's twitter feed probably isn't the right way to assess this because i suspect you may get a vitriolic twitter feed a nyway may get a vitriolic twitter feed anyway and i would be hopeful that would see it contained. professor colin, we appreciate your time is the early in the morning. needless to say we will keep an eye on this story and update you on all so. in other news: it's europe's biggest airline by passenger numbers and now, ryanair has created a massive pr nightmare for itself. the budget carrier announced on saturday that it would cancel 40—50 flights every day for the next six weeks. why? well, they're facing a massive backlog of staff leave, which means their pilots need to take holidays. the debacle has left tens of thousands of passengers stranded. 160 flights were cancelled over the weekend at the last minute, and on sunday, the airline revealed it will cancel 164 flights over the next three days, potentially affecting 30,000 passengers. general motors will recall 2.5

a trend for years. but in singapore, kids are connecting with robots at a very young age. here at school for kids kindergarten, this four, five and six learning the building blocks of computer programming. elyce is six years old and she is showing me how it works. she is programming the robot with a set of instructions made from each block. what do you like about the robot? the torah bright can dance on the rank the robot can have liked! —— the robot can dance! the robot has lights the robot kit the kids are using is called keybo, just one of the technology toys being used in the classroom. 10% of the schools in singapore have been taking part in the pilot known as play maker, costing the governmentjust over1 million us dollars but teachers think the payoff is worth it.|j

million us dollars but teachers think the payoff is worth it. i have a couple of children who lack communication skills and they are very much reserved during classroom discussions and show and tell sessions but ever since we took on play maker, ever since the habit in our curriculum, i've realised there is improvement in the way they interact with their peers. this technology does in the top kids interact, it also helps improve their 21st century skills. smart cars, smart watchers, almost every component can be programmed and we wa nt to component can be programmed and we want to increase this in the future, to not only understand how the objects work but create future objects work but create future objects and in order to do so, they need to become literate, notjust in writing and reading but literate encoding. for a lease and her classmates, these robotic toys are more thanjust

classmates, these robotic toys are more than just child's play. it is hoped that the skills these kids are learning will help them to survive in the digital world. but look at financial markets in asia who are having a good session and no big surprise that follows on from record highs friday night in the united states. we are seeing these markets a decade high. the yen fairly wea k these markets a decade high. the yen fairly weak as well. a brand—new trading week is under way and the focus for markets globally will be the federal reserve meeting tuesday and wednesday. so that is a reminder of how it all ended in the united states on friday. as i say, record highs across the board. back in a few minutes with the news review, please stay with us. sally willjoin

me shortly for the news review. there has been a big increase in the number of prosecutions for the online sexual grooming of children using evidence supplied by so—called ‘paedophile hunters.‘ in 2014, 11 % of cases featured material gathered by the groups. by last year, that figure had risen to 44%. jon cuthill has this report. the police say paedophile hunters are vigilantes, posing as children online, filling their meetings with people who groom them and post the videos on social media. meeting a 14—year—old with a sexier today? the police are on their way. i am a paedophile hunters, mate, that is what i do. you are under citizen 's arrest. in 2014, 11% of cases for meeting a child following sexual grooming contained paedophile

hunters evidence. two years later, it has grown to 44%. i think it's an embarrassing figure for british policing, but the success that is being achieved and recognise of course but the dangers of vigil in but then do something about it, and within the criminaljustice system. will there ever be a situation where they could work together with police? i think it is something that we will potentially have the lookout when it —— but it comes with complexity. not least of all the psychological screening that the professionals go through to make sure that these people are still not being adversely affected by this while i will have to look at it, the risks are really significant and cannot be understated. i will not condone these groups and i would encourage them to stop and i recognise i am not winning that conversation, i'm not winning that moral argument. the man called by this southampton —based hunter pleaded guilty and is injail awaiting sentencing. this is bbc news.
